Jim Lee received his bank statement from Bayne Bank indicating a balance of $7,980. Lee's checkbook showed a balance of $6,800. Jim noticed that checks outstanding were $1,330. The bank statement also revealed an NSF check for $120 and a service charge of $30. The reconciled balance is:
The reconciled balance is calculated by starting with the checkbook balance, subtracting outstanding checks and any bank charges or errors. In Jim Lee's case, the reconciled balance is $4,320.
Explanation:The reconciled balance for Jim Lee's bank account involves adjusting Jim's checkbook balance by accounting for any outstanding checks and any bank charges or errors. To calculate the reconciled balance, you follow these steps:
Start with the checkbook balance: $6,800.Subtract the total outstanding checks: $1,330.Subtract any bank charges or errors, in this case, an NSF (Non-Sufficient Funds) check for $120 and a service charge of $30.Add any deposits in transit or errors in the bank's favor, in this question, there are none mentioned.So, the reconciled balance would be: $6,800 (checkbook balance) - $1,330 (outstanding checks) - $120 (NSF check) - $30 (service charge) = $4,320.

Final answer:
The Empirical Rule indicates approximately 68% of data lies within 1 standard deviation of the mean, and about 95% lies within 2 standard deviations for a normally distributed set.
Explanation:
To find the proportion of heights within 1 and 2 standard deviations of the sample mean, we use the Empirical Rule or the 68-95-99.7 rule for a bell-shaped distribution. This rule states that about 68% of the data will fall within 1 standard deviation of the mean, and about 95% will fall within 2 standard deviations of the mean.
This means that for a given set of data, if you calculate the mean and standard deviation, you can expect approximately 68% of your values to lie within 1 standard deviation (either side of the mean) and about 95% to lie within 2 standard deviations.
To perform this calculation, you first need to calculate the unrounded mean and standard deviation of your data set. Once calculated, you can then state, based on the Empirical Rule, that approximately 0.68 or 68% of the data is within 1 standard deviation of the mean and 0.95 or 95% is within 2 standard deviations, given the data is normally distributed.

Which type of function best models the data shown on the scatterplot?
To solve the problem we must know about quadratic equations.
The type of function best models the data shown on the scatterplot is a quadratic function.
Graph of a Parabolic functionThe graph of a quadratic function is a curve that is in the shape of a parabola. the highest point or the lowest point of the curve is known as the vertex of the parabola.The leading coefficient decides the opening of the parabola therefore if the leading coefficient is positive the parabola will open upside while downside if the leading coefficient is negative.The example of a quadratic equation is given below in the image.
Data showed of the scatterplotAs we can see the data on the scatter plot is also a parabolic shape with vertex at x = 4, and opening downwards, therefore the leading coefficient of the function is negative.Hence, the type of function best models the data shown on the scatterplot is a quadratic function.

Select each equation that has NO real solution!
To determine equations with no real solutions, assess for a negative discriminant or no x-intercepts in quadratic equations. Steps include identifying unknowns, choosing appropriate equations, simplifying terms, and checking for reasonableness.
Explanation:To select each equation that has NO real solution, we must assess the equations provided, looking for specific characteristics that indicate the absence of real solutions. One of the hallmarks of such equations is when they represent a quadratic equation with no x-intercepts or the discriminant (b^2 - 4ac) in the quadratic formula is negative, which means the roots are complex numbers.
When working on problems like these, it's crucial to go through several steps: Identify the unknown, identify the knowns, choose an equation, eliminate terms to simplify the algebra, and then check the answer to see if it is reasonable.
Let's use an example equation: x^2 + 4 = 0. To determine if this has real solutions, we can identify the unknown (x), the knowns (coefficients of x), solve the equation or calculate the discriminant (4^2 - 4*1*-4 = 16 +16 = 32, which is positive), and confirm whether the solutions are real or not. In this case, because the discriminant is positive, this equation does have real solutions, and therefore would not be included in a list of equations with no real solutions.
The equations 2x² - 4x + 5 = -3, x² - 12x + 60 = 12, and x² + 3x + 6 = 0 have no real solutions, based on their negative discriminants.
We need to determine the discriminant (b² - 4ac) of each equation to check for real solutions. A negative discriminant indicates no real solutions.
Equations Analysis
2x² + 2x = 2: Rewrite as 2x² + 2x - 2 = 0. Here, a = 2, b = 2, c = -2. The discriminant is 2² - 4(2)(-2) = 4 + 16 = 20 (positive, so there are real solutions).2x² - 4x + 5 = -3: Rewrite as 2x² - 4x + 8 = 0. Here, a = 2, b = -4, c = 8. The discriminant is (-4)² - 4(2)(8) = 16 - 64 = -48 (negative, so there are no real solutions).x² - 12x + 60 = 12: Rewrite as x² - 12x + 48 = 0. Here, a = 1, b = -12, c = 48. The discriminant is (-12)² - 4(1)(48) = 144 - 192 = -48 (negative, so there are no real solutions).x² - 4 = 0: This is already in quadratic form with a = 1, b = 0, c = -4. The discriminant is 0² - 4(1)(-4) = 16 (positive, so there are real solutions).x² + 3x + 6 = 0: Here, a = 1, b = 3, c = 6. The discriminant is 3² - 4(1)(6) = 9 - 24 = -15 (negative, so there are no real solutions).Equations with No Real Solutions

Let us say Amelia has y number of quarters and x number of nickel coins.
So total she has 15 coins.
[tex] x+y=15 [/tex]
[tex] x=15-y [/tex].................(1)
Now she has total amount = $2.15
1 dollar = 20 nickels and 1 dollar = 4 quarters
1 nickel = 0.05 dollar and 1 quarter = 0.25 dollar
so we can say that in terms of dollars,
[tex] 0.05x + 0.25y =2.15 [/tex].................. (2)
Plugging x from (1) in (2)
[tex] 0.05(15-y) + 0.25y =2.15 [/tex]
On solving we get ,
y=7
x=15-y =15-7 = 8
Answer: There are 8 nickels and 7 quarters.
Amelia has 7 quarters and 8 nickels, totaling $2.15 with 15 coins in total.
Let's solve it step by step.
Let's denote:
- [tex]\( Q \)[/tex] as the number of quarters.
- [tex]\( N \)[/tex] as the number of nickels.
Given that Amelia has a total of 15 coins, we can write the equation:
[tex]\[ Q + N = 15 \][/tex]
We're also given that the total value of her coins is $2.15. Since each quarter is worth $0.25 and each nickel is worth $0.05, we can write another equation for the total value:
[tex]\[ 0.25Q + 0.05N = 2.15 \][/tex]
Now, we can use these two equations to solve for [tex]\( Q \)[/tex] and [tex]\( N \)[/tex].
Step 1: Solve the first equation for [tex]\( Q \)[/tex]:
[tex]\[ Q = 15 - N \][/tex]
Step 2: Substitute this expression for [tex]\( Q \)[/tex] into the second equation:
[tex]\[ 0.25(15 - N) + 0.05N = 2.15 \][/tex]
Step 3: Distribute and solve for [tex]\( N \)[/tex]:
[tex]\[ 3.75 - 0.25N + 0.05N = 2.15 \][/tex]
[tex]\[ 3.75 - 0.20N = 2.15 \][/tex]
[tex]\[ -0.20N = 2.15 - 3.75 \][/tex]
[tex]\[ -0.20N = -1.60 \][/tex]
Step 4: Divide both sides by -0.20 to solve for [tex]\( N \)[/tex]:
[tex]\[ N = \frac{-1.60}{-0.20} \][/tex]
[tex]\[ N = 8 \][/tex]
Now that we know Amelia has 8 nickels, we can substitute this value back into one of the original equations to solve for [tex]\( Q \).[/tex]
Step 5: Use the first equation to solve for [tex]\( Q \)[/tex]:
[tex]\[ Q = 15 - 8 \][/tex]
[tex]\[ Q = 7 \][/tex]
So, Amelia has 7 quarters and 8 nickels.

Lily swims a 100meter race she swims the first half 27.8 she swims the second half in 30.12 seconds how much longer does it take her to swim the second half on the race than the first half
Answer: 2.32 seconds.
Step-by-step explanation:
Knowing that:
Lily swims the first half of the 100 meters race in 27.8 seconds. Lily swims the second half of the 100 meters race in 30.12 seconds.You can calculate how much longer it takes to her to swim the second half than the first half, by subtracting 30.12 seconds and 27.8 seconds.
Then:
[tex]30.12\ seconds-27.8\ seconds=2.32\ seconds[/tex]
Therefore, it took her 2.32 seconds longer to swim the second half on the race than the first half.
Answer:
2.32 seconds.
Step-by-step explanation:
We have been given that Lily swims a 100 meter race. She swims the first half 27.8 seconds and she swims the second half in 30.12 seconds.
To find how much longer it took Lily to swim the second half on the race than the first half, we need to subtract the time taken by Lily on first half from the time taken by Lily on second half.
[tex]\text{Difference of time}=30.12\text{ seconds}-\text{27.8 seconds}[/tex]
[tex]\text{Difference of time}=2.32\text{ seconds}[/tex]
Therefore, it took Lily 2.32 seconds more to swim the second half on the race than the first half.
Determine the intercepts of the line. -6x+3y=-7
For the equation -6x+3y = -7, x intercept is at (7/6, 0) and y-intercept is at (0, -7/3).
To determine the intercepts of the line described by the equation -6x+3y=-7, we will find both the x-intercept and the y-intercept. The x-intercept is found by setting y=0, and solving the equation for x, while the y-intercept is found by setting x=0 and solving for y.
For the x-intercept:
Set y=0 in the equation: -6x+3(0) = -7.Simplify and solve for x: -6x = -7.Divide by -6: x = 7/6 or approximately 1.167.For the y-intercept:
Set x=0 in the equation: -6(0)+3y = -7.Simplify and solve for y: 3y = -7.Divide by 3: y = -7/3 or approximately -2.333.So the x-intercept is at (7/6, 0) and the y-intercept is at (0, -7/3).

What is the probability that a card randomly drawn from a standard deck of 52 cards is NOT a king?
Answer : The probability for not a king is, [tex]\frac{12}{13}[/tex]
Step-by-step explanation :
Probability : It is defined as the extent to which an event is likely to occur. That means, it is measured by the ratio of the favorable outcomes to the total number of possible outcomes.
[tex]\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of favorable outcomes}}[/tex]
Favorable outcomes are, 52
Now we have to calculate the probability for not a king.
Total number of king in a deck of 52 cards = 4 (spade, heart, diamond and club)
Favorable outcomes for NOT a king = 52 - 4 = 48
Total number of outcomes = 52
[tex]\text{Probability}=\frac{\text{Number of favorable outcomes for a multiple of 3}}{\text{Total number of favorable outcomes}}[/tex]
[tex]\text{Probability}=\frac{48}{52}[/tex]
[tex]\text{Probability}=\frac{12}{13}[/tex]
Therefore, the probability for not a king is, [tex]\frac{12}{13}[/tex]
